Carvedilol shown to have unique characteristics among beta blockers
In a new study, researchers report that a class of heart medications called beta-blockers can have a helpful, or harmful, effect on the heart, depending on their molecular activity. view more (2009-11-23)
Effect of real-time CPR feedback reported at resuscitation science symposium
Emergency medical service (EMS) providers in the United States assess an estimated 350,000 cardiac arrests each year. Only 5 to 10 percent of people who have sudden cardiac arrest survive. Better quality cardiopulmonary resuscitation (CPR) provided by prehospital EMS providers may be associated with better patient outcome. view more (2009-11-23)
Drug for erectile dysfunction improves heart function in young heart-disease patients
Heart function significantly improved in children and young adults with single-ventricle congenital heart disease who have had the Fontan operation following treatment with sildenafil, a drug used to treat erectile dysfunction and pulmonary hypertension, say researchers from The Children's Hospital of Philadelphia. view more (2009-11-19)
Inhibition of GRK2 is protective against acute cardiac stress injuries
Inhibition of a protein known to contribute to heart failure also appears to be protective of the heart in more acute cardiac stress injury, namely ischemia reperfusion. view more (2009-11-18)
Fat collections linked to decreased heart function
Researchers from Boston University School of Medicine (BUSM) have shown that fat collection in different body locations, such as around the heart and the aorta and within the liver, are associated with certain decreased heart functions. view more (2009-11-16)
Young athletes need dual screening tests for heart defects, study suggests
To best detect early signs of life-threatening heart defects in young athletes, screening programs should include both popular diagnostic tests, not just one of them, according to new research from heart experts at Johns Hopkins. view more (2009-11-16)
Continuous chest compression-CPR improved cardiac arrest survival in Arizona
The chance of surviving a cardiac arrest outside a hospital was found to be twice as high when bystanders performed continuous chest compressions without mouth-to-mouth breathing than when bystanders performed standard CPR. view more (2009-11-16)
Expert on terrorism warns about the implantation of radical Islamism in Spain since 11-M
Jihadist networks "have been trying to implement their structure in Spain" since the 2004 Madrid train bombings, and therefore it is necessary for police authorities to "design and implement solutions to reduce the magnitude of the jihadist structural phenomenon in Spain". view more (2009-11-12)
Size matters: Obesity leading risk factor of left atrial enlargement during aging
Aside from aging itself, obesity appears to be the most powerful predictor of left atrial enlargement (LAE), upping one's risk of atrial fibrillation (the most common type of arrhythmia), stroke and death. view more (2009-11-10)
Less than 1 in 3 Toronto bystanders who witness a cardiac arrest try to help: Study
Researchers at St. Michael's Hospital working in conjunction with EMS services, paramedics and fire services across Ontario found that a bystander who attempts cardiopulmonary resuscitation (CPR) can quadruple the survival rate to over 50 per cent. view more (2009-11-09)
NHLBI stops enrollment in study on resuscitation methods for cardiac arrest
Enrollment has ended early in a large, multicenter clinical trial comparing two distinct resuscitation strategies delivered by emergency medical service (EMS) providers to increase blood flow during cardiac arrest. view more (2009-11-09)
New class of molecules may help prevent fatal complication in patients with kidney disease
Researchers at the University of Maryland School of Medicine have made an important discovery about why potassium builds up to dangerous levels in the bloodstream, a relatively common medical problem that affects about eight percent of hospitalized patients. view more (2009-11-04)
New methods found useful for diagnosing myocarditis
Myocarditis is an important, and often unrecognized cause of dilated cardiomyopathy (DCM). Several new diagnostic methods, such as cardiac magnetic resonance imaging (MRI), are useful for diagnosing myocarditis, according to a study published in the November 2009 issue of Mayo Clinic Proceedings. view more (2009-11-04)
Researchers develop innovative imaging system to study sudden cardiac arrest
A research team at Vanderbilt University has developed an innovative optical system to simultaneously image electrical activity and metabolic properties in the same region of a heart, to study the complex mechanisms that lead to sudden cardiac arrest. view more (2009-11-02)
Experts unveil new CVD guidelines and position papers
Several new guidelines and position papers offering the most up to date information to ensure that clinicians practice evidence-based medicine were released at the Canadian Cardiovascular Congress 2009 this week. view more (2009-10-28)
Mayo Clinic study shows people with heart devices can 'digest' advanced diagnostic technology safely
A new Mayo Clinic study suggests that video capsule endoscopy (CE), a procedure that uses wireless technology in diagnosing intestinal disease, is safe for patients with heart devices. view more (2009-10-27)
Concurrent imaging of metabolic and electric signals in the heart
Cardiac rhythm disorders can result from disturbances in cardiac metabolism. These metabolic changes are tightly linked with specific cardiac electrophysiology (CEP) abnormalities, such as depressed excitability, impaired intra- and extracellular conductivities, wave propagation block, and alteration of conduction velocity, action potential... view more...

Suppressing a gene in mice prevents heart from aging, preserves its function
Scientists prevented age-related changes in the hearts of mice and preserved heart function by suppressing a form of the PI3K gene, in a study reported in Circulation: Journal of the American Heart Association. view more (2009-10-13)
Gene mingling increases sudden death risk
A multi-national research team has discovered that two genetic factors converge to increase the risk of sudden cardiac death. view more (2009-10-13)
Patients who received donated pacemakers survive without complications
Patients who received refurbished pacemakers donated from Detroit area funeral homes survived without complications from the devices, according to a case series reported by the University of Michigan Cardiovascular Center. view more (2009-10-09)
